Potassium Nitrate
Potassium Nitrate exporter and supplier in various packing size.
Potassium Nitrite is white to gray crystalline solid. Water soluble. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers.
Potassium nitrate suitable for multiple uses.
Reactivity Alerts
Strong Oxidizing Agent
Air & Water Reactions
Soluble in water.
Fire Hazard
Special Hazards of Combustion Products: May produce toxic nitrogen oxides upon decomposition.
Behavior in Fire: Strong oxidizer which may react explosively when mixed with reducing agents. Mixture may detonate by heat or shock. Increases the flammability of any combustible material. (USCG, 1999)
Health Hazard
Exposure can cause mild irritation of eyes, nose and throat. (USCG, 1999).
